The invention consists in that the oil level is indicated via a measuring rod which is firmly connected to a float. The oil level is indicated by a marking and can be read off directly. The measuring device can be accommodated either in a side chamber of the engine housing or inserted as an accessory instead of the customary dipstick.
Patent DE-3217013-A1 (DE)
Title: Hydrostatic and hydrodynamic drive by a two-stroke diesel engine with opposing free pistons and hydraulic pump
Inventor: WAGNER ALBERT
IPC: F02B75/02
Filed: 1982-05-06
Abstract: In these drives the reciprocating movement of the free pistons of the diesel engine (1) is converted by the hydraulic oil or water delivered by the hydraulic pump (3) into rotary motion using a hydraulic motor (20) or a free jet turbine. Of simple construction without crank drive and cylinder head, and with complete counterbalancing in each cylinder, quiet running and low friction and cooling losses, these drives have the advantages, compared to the known four-stroke diesel engines, that the weight per unit power and the specific fuel consumption are lower because the hydraulic motor and the free jet turbine are lighter and have a greater efficiency than the crank drive at high delivery pressures and high speeds. In the case of automatic control of the injection quantity by the delivery pressure of the hydraulic pump, the speed in the case of the hydraulic motor is controlled by switching of the diesel engine and briefly by reducing the delivery quantity by means of a throttle valve, and in the case of the free jet turbine by adjusting of the nozzle needles and by switching of the diesel engine. The proposed drives are suitable for vehicles, ships, conveying equipment, pumps, compressors and generators.

Title: Device for a gambling machine with coin and operating control operation
Inventor: GAUSELMANN PAUL
IPC: G07F17/32
Filed: 1982-05-29
Abstract: A gambling machine with switching contacts (M and B1, B2) operated by coins and operating controls is equipped with a random circuit (27-41), which can be started by coin contact (M), and a time circuit (1-9) which can be event triggered and retriggered by the operating control contact (B1, B2). The circuits (27-41 and 1-9) decide on the triggering of a free-game signal, for which purpose the random-number circuit (27-41) carries out a dice-throwing process after the coin has been inserted, and the time circuit (1-9) generates the free-game trigger signal after its on-time has elapsed. The circuits (27-41 and 1-9) are preferably connected to free-game signalling elements (40 and 26). The random-number circuit can contain a ring counter (38), the counting stages of which are connected to the free-game signalling element (40) and other signalling elements (39), as a result of which the dice-throwing process is apperceptible. <IMAGE>

Title: Aluminium-plastic windows
Inventor: HEIGL RICHARD
IPC: E06B3/263
Filed: 1982-06-25
Abstract: Aluminium-plastic windows, comprising a window frame and a window casement, the parts of which directed inwards into the room are formed at least partially by plastic profiled sections and the parts of which directed outwards into the open form an outer shell which comprises aluminium profiles and is connected to the plastic profiles, which are provided with a reinforcement or armouring. Such a window is to be designed in such a way that the required reinforcement or armouring of the plastic profiled sections which, as the parts forming the inner shell of the window are connected to the parts forming the outer shell and comprising aluminium profiles, is to be accomplished much more simply and consequently also less expensively. This takes place by the aluminium profiles themselves forming the reinforcement or armouring for the plastic profiles and, for this purpose, having a part which comprises a box-shaped hollow profiled section which extends in the direction of the window frame or window casement and the outwardly directed sides of which form the outer shells of the casement or frame and over the upper side and under side of which the plastic profiled section is pushed, which for this purpose has on its outwardly facing side a U-shaped depression, extending in the direction of the frame or casement, and forms on its inwardly directed side the inner shell of the frame or casement.

Patent DE-3239353-A1 (DE)
Title: Valve seat ring for an intake port of valve-controlled internal combustion engines
Inventor: ZATECKY JOSEF DIPL ING
IPC: F01L3/22
Filed: 1982-10-23
Abstract: The passage opening of a valve seat ring for the intake port of valve-controlled internal combustion engines is designed in such a way that a swirling motion can be impressed upon the combustion air flowing through. In this arrangement, the passage opening is bounded on one side by a part of the outer surface of an annular bead, which outer surface, starting from the narrowest point of the annular bead, widens in a funnel or trumpet shape concentrically towards the surface of the valve seat ring. The other part of the passage opening is bounded by a portion of a circular-cylindrical wall surface formed by an eccentric turned recess, parallel to the axis, in the valve seat ring, this operation involving the partial machining away of the annular bead. That part of the annular bead which has not been machined away projects into the intake port and ensures separation- free deflection of the airflow in the direction of the valve seat. In the region of the circular-cylindrical wall surface, this deflection is less successful, thereby making it possible to impress a desired swirling motion on the air flowing through.
Patent DE-3243159-A1 (DE)
Title: Theft-proof and falsification-proof motor vehicle number plate
Inventor: MENSCH GERHARD
IPC: B60R13/10
Filed: 1982-11-23
Abstract: The theft-proof and falsification-proof motor vehicle number plate can replace the previous aluminium number plates. It is absolutely falsification-proof, consists of plastic such as already used today in motor vehicles, and is completed by numberplate stamping as hitherto. Said number plate consists of a baseplate and individual prism segments into which the letters, numbers etc straight from the manufacturer are worked. By means of the technology it is impossible to carry out changes at the individual segments because they are immediately visible. At the point of registration, the oblique stroke located between the code for the locality and the registration number is administered and issued there. After the number is assigned, the vehicle owner then receives the hyphen and goes with this to the number plate stamper. Here, from the numbers, letters and baseplates stored there, the number plate is indelibly welded using ultrasonic sound. (Without the hyphen, the segment also has a different prism grinding and a numberplate stamper cannot produce a number plate). Behind the attachment screws there are two ampoules with fluid which, if the number plate is removed violently or intentionally, are destroyed for example by the securing impact screw Patent Application Number P 3230973.2 and make the motor vehicle number plate unusable. As a result, the protection against theft required by the law is also ensured.

Title: Arrangement for the compensation of thermally induced displacements of work spindles on processing and fabricating machines
Inventor: FUNKE WOLFGANG DIPL ING
IPC: B23Q11/14
Filed: 1983-03-11
Abstract: The invention relates to an arrangement for the compensation of thermally induced displacements of work spindles on processing and fabricating machines, in particular machine tools, as a result of thermal deformations at the sub-assemblies of the work-spindle bearings or at the headstocks. The aim of the invention is to achieve a high accuracy of the axial position of work spindles with little technical outlay, in which case the object is to compensate displacements of the work spindles without the additional use of heating and/or cooling units and while using the existing lubricating and/or bearing-pretensioning devices. According to the invention the object is achieved by sensors being arranged at the bearing points or near the bearing points guiding the work spindles, which sensors are connected to the input of a computer of a computer-integrated control system as an analysing means, which computer is in turn coupled on the output side to the bearing points, via one or more final control elements, for a single-loop or multi-loop control circuit. <IMAGE>
